  2. Oil additive - Wikipedia

    en.wikipedia.org/wiki/Oil_additive

    Oil additives are vital for the proper lubrication and prolonged use of motor oil in modern internal combustion engines.Without many of these, the oil would become contaminated, break down, leak out, or not properly protect engine parts at all operating temperatures.

  3. Heat-transfer fluid - Wikipedia

    en.wikipedia.org/wiki/Heat-transfer_fluid

    Water is the most common heat transfer fluid because of its economy, high heat capacity and favorable transport properties. However, the useful temperature range is restricted by freezing below 0 °C and boiling at elevated temperatures depending on the system pressure. Antifreeze additives can alleviate the freezing problem to some extent ...

    Salen is a typical metal-deactivator. Metal deactivators, or metal deactivating agents (MDA) are fuel additives and oil additives used to stabilize fluids by deactivating (usually by sequestering) metal ions, mostly introduced by the action of naturally occurring acids in the fuel and acids generated in lubricants by oxidative processes with the metallic parts of the systems.

  7. Lubricant - Wikipedia

    en.wikipedia.org/wiki/Lubricant

    Typically various filtration systems remove particulates, additives, and oxidation products and recover the base oil. The oil may get refined during the process. This base oil is then treated much the same as virgin base oil however there is considerable reluctance to use recycled oils as they are generally considered inferior.

  8. Drag reducing agent - Wikipedia

    en.wikipedia.org/wiki/Drag_reducing_agent

    Drag reducing agents have been found useful in reducing turbulence in the shipbuilding industry, for fire-fighting operations, oil-well fracturing processes, [5] in irrigation systems and in central heating devices. Drag reducers can work in a couple of different fields. The most popular are crude oil, refined products and non-potable water ...

  9. Gel point (petroleum) - Wikipedia

    en.wikipedia.org/wiki/Gel_point_(petroleum)

    Anti-gel additives are sometimes added to petroleum products where cold temperature may affect their use. The additives act to reduce the formation of wax crystals in the product, thereby lowering the pour point and the gel point of the fuel. Anti-gel additives may not necessarily affect the cloud point.
